Be careful what you trust off a G1000 in a 172 as well
Plus I asked the instructor exactly how it did the wind calculation. He thought it included an assumption that you were flying forwards, ie motion
through the air was in the direction you were headed, ie there was no correction for flying out of balance.
If correct, that says to me that if you choose to fly out of balance you had better not take the G1000's calculation of wind very seriously. I haven't actually experimented by flying the 172 sideways on purpose and seeing how what the G1000 reports for wind changes.
